Your weedfins have a good reputation Wolfgang, but I don't think many of our locals would want to splash out on a new quad waveboard if it proved necessary to replace all the fins with weeders.

By all accounts the size and placement of the four fins is already some sort of black art requiring a box load of spares (judging by what others say on various forums) so why not stay single! We can't all be world champions, and my single fin Evo still works well enough.
